POUR-OUT FOR BOTTLES.

Specification of Letters Patent.

Patented July 15, 1919.

Application filed November 29, 1913, Serial No. 803,704. Renewed February 24, 1919. Serial No. 278,931.

'1 '0 all whom it may concern:

Be it known that I, WILLIAM I)EPPER- MANN, a citizen of the United States of America, and a resident of the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Pour-Outs for Bottles, of which the following is a full and clear specification.

My invention relates to pour-outs for bottles or other containers for ink or the like. The invention relates particularly to that class of pour-outs in which the flow of liquid through the liquid vent is controlled by opening and closing an auxiliary air vent of relatively smaller diameter than the liquid vent. By placing the finger over the air vent the How of liquid is effectually stopped.

n object of my invention is to provide a device of this character which will effectively seal the bottle, after filling with ink or the like, and prevent leakage when the bottle is being carried in other than an upright position. A further object is to provide means whereby a simple manipulation of a movable part will make the bottle ready for use. Further objects will be pointed out in the following description and claims.

In the drawings I have illustrated a pourout for ink bottles,

Figure 1 representing in vertical section a referred form of my device;

ig. 2 is a front view of the same;

Fig. 3 is a rear View of the same;

Fig. 4 is a view In section on the line Fig. 5 a bottom view of the upper member of my device;

Fi. 6 is a top view of the lower mem er;

Fi. 7 a bottom view of the lower Fi 10 is a vertical section of another modi cation;

Fig. 11 is a detail vertical section of another modification;

Fig.- 12 is a detail vertical section of an other modification;

Fig. 13 is a perspective view of another modification The same reference characters are used to denote similar parts in all the views.

Referring more particularly to the form of the device shown in Figs. 1 to 7 inclusive. 1 is the neck of a bottle or other container, having the usual flange 2. The pour-out is divided on a horizontal lane into the up per member 3 and the ower member 4'. Within the pour-out are located the liquid rent or passage 5 terminating in the spout (5. and the air vent or passage 7. Within the recess 8 on the bottom face of the upper member 3 I place a washer having two perforations to correspond in size and position to the vents 5 and 7. The washer may be readily secured to the upper member 3 by cement or the like or, as shown in Fig. 5, the recess 8 may be hexagonal or any other non-circular shape, the Washer being cut in the same shape and size. It is essential that the washer 8 be in positive engagement with either the upper or lower member in order that the vents may be accurately thrown open or closed at will. Fig. 13 illustrates one of a number of additional ways in which this can be done. In this arrangement the view being a perspective view of the lower member. the washer 8 (not shown) is adapted to be held by the lugs 17 making it possible to use a circular washer in a circular recess or omitting the recess altogether. Moreover the lug 17 may be put either on the lower mom or or on the upper member. It will be noted that the air vent 7 is enlarged for a portion of its length or in other words has. a reduced finger closed inlet. Experiment has shown me that if the air vent 7 is. made of uniform bore throughout, the flow of liquid from the liquid vent 5 is diflicult to regulate, both as to quantity and direction, as the liquid will come out in a succession of spurts. I also find this construction of the air vent 7 desirable to prevent the closing of the air vent by any failure to register the perforation in the washer accurately with the air vent or by any roughness of the washer which might close the air vent if it were made narrow throughout its length.

Means for fastening the pour out to the bottle 00 prises an embracing ring 9 prefmay 0 sheet ni'etah The lower edge of the ring is turned in to engage the flange 2 of the bottle and is bent inwardly at 10 to hold the lower member 4 under 'pressure, against washer 11, thereby instiring'a tight seal at this point. The upper rim of the ring is also turned inwardly to loosely engage the shoulder 12 of the upper member 3.

It will he semi that since the lower them her I is rigidly clmnpcd lo the bottle neck and tluupper member {5 is loosely held within the ring I), the upper member 3 can be rotated on the lower member 4-, thereby throwing out of register the sections of the vents 5 and 7 This operation cooperating with the washer 8 effectively seals the bottle. The upper member 8 is so shaped as to facilitate grasping it between the fingers, as shown in Fig. 2. It is obvious, moreover, that a very slight displacenumt of the parts will sutlice to seal the bottle. I have found that a quarter turn of the upper member 3 n, quite sufficient for this purpose. In order Io insure the accurate registry of the vents i the upper and lower members, 1 have provided on the button] of the upper mem her 3 a segmental lug 13, and on the top of the lower member 4 is a segmental recess 14. The segmental lug 13 is adapted to travel within the segmental recess 14. The vents canbe quickly brought into. registry by rotating the upper member 3 until the segmental lug 13 reaches the end of the segmental recess 14. The condition of the pour-out, whether open or shut, can be ascertained by reference to the indicator shown in Fig. 2, being noted in the position of the index 15 its relation-to the Words Open and Shut which are stamped into the ring 9. The index 15 being secured to the upper member 3 will turn with it and thereby indicate from its position whether the pour-out is open or shut. It is, of course, necessary for the arrurato working of this indicator that the relation of the ring 9 to the lower member 4 should-be determined. For this purpose I put one or more beads 16 on the lower member 4, these beads being adapted to fitinto corresponding grooves on the ring 9, as shown'in Figs. band 7. For the purpose of preventing ink from being held in the liquid vent 5 by prefer to make the lower vent flaring. It is important that this liquid vent should he kept drained. otherwise any rise in temperature due to moving the bottlefrom a cold to a warm place, would generate a pressure Within the bottle which may be sufficient to force a few drops through the liquid vent 5 as soon as is opened.

In Figs. 8, and 9, I have illustrated a modification in which the lower member 4 is made in the form ofa cork-which tightly fits within the neck of a bottle. I he Ori i dly' enga es-and turns withtheup er mem er 3 'by t e arrangement Shown in 1g.

capillary attraction, I end'of the liquid ring 9, the ring being formed square at its upper edge and closely engaging the sides of the square portion of the upper member 3. The lower member 4- being in loose engagement with the ring 2), rotation between the memhers is permitted.

in Fig. 10 I have illustruttnl another method of fastening the pour-out to the bottle. an exlvrnal thread being molded on the neck of lhe bottle and a corresponding internal thread on the lower member 4. in this modification the engagement of the ring D with the upper member 3 is ri id and with the lower member 4 is loose. fill this figure I have also shown a modification of the spout (3 for filling fountain pen barrels or containers having small openings. It will be seen that the spout is extended out and tapered to enable it to be inserted in the pen barrel or the like.

As shown in Fig. 11, the arrangement may be reversed by putting the internal thread on the neck f the bottle and the extcrnal thread on the inserted portion of the l\')\\'('l' ll l mllpl' In Fig. 12 l have illustrated a variation of the means for draining the liquid vent 5 which consists in making an oblique termi nation to the liquid rent at its lower end, the draining effect being enhanced by a notch or notches 18. Without departing from the spirit of the invention I may also drainthe liquid vent 3 by having it taper from the top to the bottom instead of flaring at the bottom as'shown in Fig. 1.

While I have illustrated a bottle fitted with my pour-out device for dispensing ink, it will of course, be understood that the in vention can be applied to various containers for dispensing various liquids.

I claim:
